FIELD AND BACKGROUND OF THE INVENTION

The present invention, in some embodiments thereof, relates to optimizing discovery of a high resources consuming wireless network resource for a group of mobile communication devices, and, more specifically, to optimizing resources consumption during discovery of a high resources consuming wireless network resource within a group of mobile communication devices.

Availability and distribution of mobile wireless network-enabled devices is rapidly increasing. The wireless network-enabled devices such as, for example, a mobile phone, a tablet, a laptop, a smart watch, a wearable device and the likes are mostly battery powered and hence may have a limited battery capacity, i.e. having limited battery energy and/or battery power. In addition the mobile wireless network-enabled device(s) may have limited processing and/or computation resources. The mobile wireless network-enabled device(s) may support communication over one or more high resources consuming wireless networks such as, for example, wireless local area network (WLAN) also known as Wi-Fi, Worldwide Interoperability for Microwave Access (WiMAX), cellular network and the likes. In addition to the ability to connect to the one or more high resources consuming wireless networks, two or more of the mobile wireless network-enabled devices may share another one or more low resources consuming communication links. The low resources consuming communication links may be, for example, Bluetooth low energy (BLE also known as Bluetooth smart), Bluetooth, near field communication (NFC), infra-red (IR), ZigBee and/or Z-Wave.

Constant connection of the one or more network-enabled devices to the one or more high resources consuming wireless networks, and specifically, a network discovery session in which the network-enabled device(s) discovers and/or resolves availability of a network connection to the one or more global networks and/or one or more remote network resources may involve high resources consumption.

Moreover, a scenario in which the network-enabled device(s) are trying to discover availability of the high resources consuming wireless network(s) in a location where there is no coverage for the high resources consuming wireless network(s) may result in excessive battery energy consumption. Unless the high resources consuming wireless network interface of the network-enabled device(s) is manually turned off the network-enabled device(s) may try to automatically discover the high resources consuming wireless network(s) over and over again to no avail.

DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

The present invention, in some embodiments thereof, relates to optimizing discovery of a high resources consuming wireless network resource within a group of mobile communication devices, and, more specifically, to optimizing resources consumption during discovery of a high resources consuming wireless network resources within a group of mobile communication devices by dynamically assigning a discovering master communication device.

The term high resources consuming wireless network resource in the context of the present invention relates to a high resources consuming wireless network and/or a remote resource which is accessible over a high resources consuming wireless network. The high resources consuming wireless network may be a wide area network (WAN) which utilizes an infrastructure to allow communication with remote sites and/or devices through a networking infrastructure. The WAN may utilize one or more wireless networks, for example, a wireless network connecting to the internet, a cellular network, a WiMAX and the likes. Specifically, in the context of the present invention, a wireless local area network (WLAN) may be may considered a high resources consuming wireless network resource as it allows connection to a WAN through a local infrastructure, for example, a base station, an access point, a switch, a router and the likes. The cellular network may include one or more cellular networks, such as, for example, a global system for mobile communications (GSM) network, a code division multiple access (CDMA) network and/or a long-term evolution (LTE) network. As stated, the high resources consuming wireless network resource may refer to either availability of the high resources consuming wireless network itself and/or to availability of one or more remote resources which are accessible over the high resources consuming wireless network, for example, a database, a storage, a web site, a printer and the likes. Communication over the high resources consuming wireless network is considered as high resources consuming. A low resources consuming communication link as opposed to the high resources consuming wireless network is a communication link which is a low resources consumer and is used for communication among two or more nearby communication devices through, for example, an ad-hoc connection, a network infrastructure and/or a peer-to-peer connection between two or more communication devices. The low resources consumption of the low resources consuming communication link may be absolute and/or relative to the high resources consuming wireless network. The low resources consuming communication link may include, for example, BLE, Bluetooth, NFC, IR, ZigBee and/or Z-Wave. Optionally, the low resources consuming communication link may be utilized through a wired connection and/or protocol between two or more communication devices, for example, universal serial bus (USB), Ethernet and/or token ring. Communication over the low resources consuming communication link is considered as low energy and/or power consuming. Resources consumption for communicating over the high resources consuming wireless network and/or the low resources consuming communication link are very much application dependent. However, for a given communication session involving a given bandwidth and/or throughput, energy consumption for example, of communication over the low resources consuming communication link may be as low as 2% compared to communication over the high resources consuming wireless network. Optionally, a WLAN for example may be considered a low resources consuming communication when discovering availability of higher (relative to the WLAN) resources consuming wireless network resource(s) such as, for example, a cellular network and/or a remote resource which is accessible over a cellular network.

The term resources in the context of optimizing resources during the discovery process of a high resources consuming network resource may refer to optimizing one or more resources of the group of mobile communication devices such as, for example, energy, power, battery life, processing load, processing time, execution time and the likes. Optionally, resources include network service availability, for example a valid communication package, a valid service provider package, sufficient network bandwidth and the likes.

According to some embodiments of the present invention, there are provided devices, systems, methods and computer program products for optimizing resources consumption during discovery of a high resources consuming wireless network resource for a group of mobile communication by dynamically assigning a discovering master communication device. In a scenario where two or more network-enabled communication devices are located nearby and the two or more nearby communication devices share at least some common networking capabilities a network a high resources consuming wireless network discovery session may be initiated with assigning discovering master communication device. The discovery sequence as described herein aims to optimize power consumption of the two or more communication devices which try to access a common high resources consuming wireless network resource. The common networking capabilities allow the two or more communication devices to connect to one or more common high resources consuming wireless network resources and to one or more common low resources consuming communication link. As discussed hereinabove, the high resources consuming wireless network resource may refer to availability of the high resources consuming wireless network itself and/or to availability of one or more remote resources which are accessible over the high resources consuming wireless network. However, for brevity, throughout this invention reference is made to discovery of the high resources consuming wireless network itself but is not limiting in any way. Communication between the two or more nearby communication devices is done over the one or more common low resources consuming communication links which are naturally low resources consuming links compared to communication over the high resources consuming wireless networks. The discovering master communication device may enable one or more interfaces in order to discover an available one or more of the high resources consuming wireless networks such as, for example, a WLAN, a Wi-Fi, a cellular network, a WiMAX and the likes. Methods, sequences and/or algorithms for discovering the one or more high resources consuming wireless networks by the discovering master communication device is performed as known in the art and is beyond the scope of this invention.

During the discovery process the high resources consuming wireless interfaces of the one or more nearby communication device(s) are disabled to, for example, preserve battery energy and/or reduce processing load. In the event the discovery process resolves that one or more of the high resources consuming wireless networks are available the discovering master communication device establishes a connection with the available high resources consuming wireless network(s) and sends an availability message to notify one or more of the nearby communication devices of the availability. The availability message is sent by the discovering master communication device to the nearby communication device(s) over the low resources consuming communication link, for example, BLE, Bluetooth, NFC, IR, ZigBee and/or Z-Wave. Once the availability message is received by the nearby communication device(s) they may enable corresponding high resources consuming wireless interface(s) to connect to the available high resources consuming wireless network(s). The discovering master may be assisted by the nearby communication device(s) for discovering the availability of the high resources consuming wireless resource(s). The assistance may be in the form of, for example, providing sensory data and/or calendric data retrieved from calendric data records. In case no high resources consuming wireless network was discovered, the discovering master communication device may initiate additional network discovery sessions. Optionally, a time interval may be set between successive network resources discovery sessions during which the high resources consuming wireless interface of the discovering master communication device is turned off to, for example, preserve battery energy and/or reduce processing load. The discovering master communication device may transfer the role of network discovery to one of the other one or more nearby communication devices by sending a master assignment message. Assigning the role of network discovery from the current discovering master communication device to one of the nearby communication devices may be done by employing one of a plurality of dynamic network master assignment methods, for example, random assignment and/or token ring assignment. Assigning the role of network discovery may be performed by the discovering master communication device itself or by one of the other nearby communication devices, i.e. the discovering master communication device may not necessarily be responsible for assigning the role of network discovery. Transferring the role of network discovery and assigning it to one of the nearby communications devices may be done based on an analysis of availability of one or more resources such as, for example, battery energy, battery power, battery life, processing load, processing time, execution time, valid communication package, a valid service provider package, sufficient network bandwidth and the likes for each of the nearby communications device(s). Optionally, the resources analysis may compute the impact of enabling the one or more high resources consuming wireless interfaces on one or more of the resources and/or impact of other task(s) performed by each of the nearby communications device(s) on one or more of the resources. Optionally, the resources analysis determines the network availability, for example, a valid communication package, a valid service provider package and/or sufficient network bandwidth for the one or more nearby communication devices. As described above the resources analysis may be performed by any of the nearby communications device(s) and not necessarily by the discovery master communication device. The resources analysis may be performed individually by each of the nearby communications device(s) and the results transferred to one of the nearby communications device(s) for final decision for assigning the network discovery role.

Optionally, at an event the discovering master communication device is not detected, not available and/or not properly responding on the low resources consuming communication link, a new discovering master communication device is assigned.

Optionally, one or more additional network-enabled nearby communication devices may pair and/or connect to the low resources consuming communication link and join the high resources consuming wireless network discovery session.

Optionally, the discovering master communication device disables its one or more high resources consuming wireless interfaces and avoids the network discovery session following an indication that the discovering master communication device is located in a no coverage area of the one or more high resources consuming wireless networks. The indication may originate from an indicating device which may be the discovering master communication device itself and/or received from one or more of the nearby communication devices which may use one or more of their integrated capabilities to assist the discovering master communication device in the network discovery session, for example, sensory data and/or calendric data. I.e. one or more of the nearby communication devices may assist the discovering master communication device to identify a no coverage area condition.

Optionally, the network no coverage indication source is an input from one or more sensors, for example, a global positioning system (GPS) sensor, an accelerometer sensor and/or a gyroscope sensor which may be accessible from the discovering master communication device and/or from one or more of the nearby communication devices.

Optionally, the network no coverage indication source is the result of an analysis performed over calendric information available from one or more data records and/or software application residing on the discovering master communication device and/or one or more of the nearby communication devices. The data records may include, for example, information relating to the location of the person associated with the one or more communication devices at a certain time and date. Network coverage information relating to the determined no coverage location may be retrieved from one or more remote locations such as, for example, a remote server and/or a remote database over the one or more high resources consuming wireless networks (while still in network coverage area) and/or from past experience relating to trying to discover the one or more high resources consuming wireless networks at the determined location in the past.

Optionally, the indication source for the network no coverage indication for a specific one of the one or more high resources consuming wireless networks is received from the one or more remote locations over a different one or more of the high resources consuming wireless networks. For example, information of no Wi-Fi availability (no coverage) may be received by the discovering master communication device and/or one or more of the nearby communication devices over one or more of the cellular networks, such as, for example, a GSM network, a CDMA network and/or an LTE network.

While it may desirable to have the one or more network-enabled devices constantly connected to the one or more high resources consuming wireless networks, resources consumption may be greatly reduced by optimizing the network discovery session to be handled by the single discovering master communication device while the high resources consuming high resources consuming wireless interfaces of the one or more nearby communication devices is disabled (not consuming energy for example). Furthermore, the optimized network discovery session may allow for a more balanced and/or more efficient resources consumption management among the two or more communication devices since the role of network discovery may be dynamically re-assigned at any given time to the communication device currently presenting the highest availability of one or more of the resources, for example, longest battery life expectancy, highest battery energy (power) level and/or lower processing load. Moreover, completely disabling the high resources consuming wireless interfaces of all the communication devices in the event they are located in a no coverage area may serve for even higher resources saving by avoiding the redundant process for discovering the one or more high resources consuming wireless networks in a location where they are not available. The fact that the one or more nearby communication devices may support the master discovering communication device in detecting the network no coverage area may further expand the awareness of the master discovering communication device to such network no coverage areas.

Reference is now made to FIG. 1 which is schematic illustration of an exemplary system for optimizing discovery of a high resources consuming wireless network resource by dynamically assigning a discovering master communication device, according to some embodiments of the present invention. A system 100 includes a discovering master communication device 102 and one or more nearby communication devices 104 which have networking capabilities allowing them to connect to one or more high resources consuming wireless networks 110 and to one or more common low resources consuming communication links 120. The discovering master communication device 102 and one or more nearby communication devices 104 may be mobile communication devices such as, for example, a mobile phone, a tablet, a laptop, a smart watch, wearable devices and the likes. Over the one or more high resources consuming wireless networks 110, the discovering master communication device 102 and one or more nearby communication devices 104 may access one or more of a plurality of remote resources 115 such as, for example, a database, a storage, a web site, a printer and the likes.

The discovering master communication device 102 enables a first communication interface which is a high resources consuming wireless interface to start a network discovery session to discover the high resources consuming wireless network 110 and/or availability of one or more of the remote resources 115. At the detection of availability of the high resources consuming wireless network 110 and/or one of the remote resources 115, the discovering master communication device 102 establishes connection with the high resources consuming wireless network 110. The discovering master communication device 102 may be assisted by one or more of the nearby communication devices 104 for discovering the availability of the high resources consuming wireless network 110 and/or availability of one or more of the remote resources 115. The assistance may be in the form of, for example, providing sensory data and/or calendric data retrieved from calendric data records. Once the connection with the high resources consuming wireless network 110 is established, the discovering master communication device 102 sends one or more of the nearby communication devices 104 a availability massage over the low resources consuming communication link 120 to inform them that the high resources consuming wireless network 110 is available and they may try to connect to it. The discovering master communication device 102 connects to the low resources consuming communication link 120 through a second communication interface which may be a local communication interface. Following reception of the availability massage, each of the nearby communication devices 104 may try to discover, resolve and/or establish connection with the high resources consuming wireless network 110. When the high resources consuming wireless network 110 is not discovered, the discovering master communication device 102 may initiate additional network discovery sessions. Optionally, a time interval may be set between successive network discovery sessions during which the high resources consuming wireless interface of the discovering master communication device is turned off to preserve battery energy and/or processing resources. In case the connection with the high resources consuming wireless network 110 is lost the sequence to discover the high resources consuming wireless network 110 is repeated. However at any time during the sequence to discover the high resources consuming wireless network 110 a discovering master assignment process may be executed for assigning the role of network discovery to one of the communication devices 104. The discovering master assignment process may be performed by the discovering master communication device 102 and/or by one or more of the nearby communication devices 104. The discovering master assignment process may rely on a resources analysis in which information on one or more resources, for example, energy, power, battery life, processing load, processing time, execution time and/or network availability is collected from the discovering master communication device 102 and/or one or more of the nearby communication devices 104 to identify a communication device which is currently the best candidate for the role of network discovery of the high resources consuming wireless network 110 with respect to availability of the one or more resources. The resources analysis may include computation of one or more energy and/or processing aspects for the discovering master communication device 102 and/or for each of the nearby communications device(s) 104. The resources analysis may include analysis of, for example, battery energy level, battery life expectancy, impact of enabling the high resources consuming wireless interface(s) on the battery life expectancy and/or impact of other tasks performed by each of the discovering master communication device 102 and/or the nearby communications device(s) 104 on the battery life expectancy. The resources analysis may further include analysis of network availability, for example, a valid communication package, a valid service provider package and/or sufficient network bandwidth for the discovering master communication device 102 and/or for each of the nearby communications device(s) 104. Following the resources analysis a candidate for the role of network discovery may be determined which may be assigned as a new discovering master communication device such as the discovering master communication device 102 or one of the nearby communications devices 104. In case the determined candidate for the role of network discovery is not the current discovering master communication device 102, the discovering master communication device 102 dynamically assigns the nearby communications device 104 which was determined to take the role of network discovery as a new discovering master communication device such as the discovering master communication device 102. The assignment is done through a master assignment message sent to the determined candidate over the low resources consuming communication link 120.

The discovering master communication device 102 may be the master of the low resources consuming communication link 120. Optionally, one of the other nearby communication devices 104 may be the master of the low resources consuming communication link 120. When configured as the master of the communication link 120 in case the role of network discovery is assigned to one of the nearby communication devices 104, the new discovering master communication device becomes the master on the low resources consuming communication link as well after the previous discovering master communication device has resigned mastership. Additionally and/or alternatively, the previous discovering master communication device may not resign mastership over the low resources consuming communication link 120 after it is no longer assigned as the discovering master communication device 102. The previous discovering master communication device which maintains mastership over the low resources consuming communication link 120 while the discovering master communication device 102 and the one or more nearby communication devices 104 are slave devices on the low resources consuming communication link 120. The previous discovering master communication device may perform as a coordinator between discovering master communication device 102 and the one or more nearby communication devices 104. The previous discovering master communication device may employ and/or execute a message distribution system and/or a software application which may support communicating with the discovering master communication device 102 to retrieve one or more messages concerning the network discovery session and distribute the message(s) to one or more of the nearby communication device(s) 104.

Optionally, one or more additional network-enabled nearby communication devices such as nearby communications device 104 may join the system 100 by pairing and/or connecting to the low resources consuming communication link 120 in order to participate in the network discovery session of the high resources consuming wireless network 110.

Optionally, in the event that the discovering master communication device 102 is not detected, not available and/or not properly responding on the low resources consuming communication link 120, a new discovering master communication device 102 is assigned. Assignment of the new discovering master communication device 102 may be done based on the resources analysis.

Optionally, following an indication of no coverage area for the high resources consuming wireless network 110, the discovering master communication device 102 turns off its high resources consuming wireless interface and does not try to initiate the network discovery session with the high resources consuming wireless network 110. The no coverage area indication may come from an indicating device which may be the discovering master communication device 102 and/or one or more of the nearby communications device(s) 104 which may use one or more of their capabilities, for example, sensory data and/or calendric data to assist the discovering master communication device 102 in the network discovery session.

Optionally, the network no coverage indication source is an input from one or more sensors, for example, a GPS sensor, an accelerometer sensor and/or a gyroscope sensor which may be accessible from the discovering master communication device 102 and/or from one or more of the nearby communication devices 104 assisting the discovering master communication device 102. The GPS sensor, for example, may indicate the current location is not within coverage of the high resources consuming wireless network 110. The accelerometer sensor and/or the gyroscope sensor may indicate a traveling speed which may be associated with, for example, driving a car and/or flying on an aircraft suggesting that the high resources consuming wireless network 110 may not be available. Network coverage information relating to the determined no coverage location may be retrieved from one or more remote locations such as, for example, a remote server and/or a remote database over the one or more high resources consuming wireless networks (while still in network coverage area) and/or from past experience relating to trying to discover the one or more high resources consuming wireless networks at the determined location in the past.

Optionally, the network no coverage indication source results from an analysis performed over calendric information available from one or more data records and/or software application residing on the discovering master communication device 102 and/or one or more of the nearby communication devices 104 assisting the discovering master communication device 102 in the network discovery session. The data records may include, for example, information relating to the location of the person associated with the one or more communication devices at a certain time and date, for example a calendar record and/or a calendar application. The calendar application, for example may include a record indicating that at a specific time the associated person will be travelling by bus suggesting that the high resources consuming wireless network 110 may not be available. Another example may that according to one or more calendar records every evening the associated person drives home from work on a route which was identified in the past as a no coverage area for the high resources consuming wireless network 110.

Optionally, the indication source for the network no coverage indication for a specific one of the one or more high resources consuming wireless networks 110 is received from the one or more remote locations over a different one or more of the high resources consuming wireless networks 110. The no coverage indication may be received by discovering master communication device 102 and/or by one or more of the nearby communication devices 104 which may use one or more of their integrated capabilities, for example, sensory data and/or calendric data to assist the discovering master communication device 102 in the network discovery session. For example, information of no Wi-Fi availability (no coverage) may be received by the discovering master communication device 102 and/or one or more of the nearby communication devices 104 over a cellular network, such as, for example, a GSM network, a CDMA network and/or an LTE network.

Reference is now made to FIG. 2 which is a schematic illustration of an exemplary discovering master communication device, according to some embodiments of the present invention. An exemplary discovering master communication device such as the discovering master communication device 102 includes a first communication interface 210, a second communication interface 220 , one or more processors 230 and a storage 240 which stores a program code 250. The first communication interface 210 is a high resources consuming wireless interface for connecting to a high resources consuming wireless network such as the high resources consuming wireless network 110. The second communication interface 220 is a low resources consuming communication interface for connecting to a low resources consuming communication link such as the low resources consuming communication link 120. The processor 220 is coupled to the first interface 210, to the second interface 220 and to the storage unit 240 for executing the program code 250. The processor 230 enables the first interface 210 and starts a network discovery session to discover a remote resource, for example, the high resources consuming wireless network 110 and/or one or more remote resources accessible over the such as the remote resources 115. In the event the remote resource is detected the processor 230 tries to establish a connection to the remote resource. Once the connection to the remote resource is established the processor 230 send an availability message to one or more nearby communication devices such as the nearby communication devices 104 (FIG. 1) (yes, reference is made to devices such as those described in FIG. 1) over the low resources consuming communication link 120 using the second interface 220.

In the event that a new discovering master communication device is assigned, for example following an resources analysis of the discovering master communication device 102 and the one or more nearby communication devices 104, the discovering master communication device 102 sends a master assignment message to the new discovering master communication device over the low resources consuming communication link 120 and resigns the role of being the discovering master communication device 102.

In some embodiments of the present invention, the discovering master communication device 102 performs as the master of the low resources consuming communication link 120. When the role of network discovery is assigned to one of the nearby communication devices 104, the new discovering master communication device becomes the master on the low resources consuming communication link after the discovering master communication device 102 resigns mastership.

In another embodiment of the present invention, there is no relation between the role of network discovery and mastership over the low resources consuming communication link 120. In case the discovering master communication device 102 is the master of the low resources consuming communication link 120 and a new discovering master communication device is assigned the discovering master communication device 102 may not resign mastership over the low resources consuming communication link 120 after it is no longer assigned as the discovering master communication device 102. The previous discovering master communication device may employ a message distribution system and/or application to receive messages from the discovering master communication device 102 and distribute them to the nearby communication device(s) 104.

Reference is now made to FIG. 3 which is flowchart of an exemplary process for optimizing discovery of a high resources consuming wireless network resource by dynamically assigning a discovering master communication device, according to some embodiments of the present invention. As shown a process 300 for optimizing discovery of a high resources consuming wireless network by dynamically assigning a discovering master communication device may be implemented through a system comprising two or more nearby network-enabled communication devices such as the system 100. The process 300 starts by a discovering master communication device such as the discovering master communication device 102 enabling a high resources consuming wireless interface such as the first interface 210.

As shown at 320, the discovering master communication device 102 initiates a discovery session to discover availability of a high resources consuming wireless network such as the high resources consuming wireless network 110 and/or one or more remote resources such as the remote resources 115. The discovering master communication device 102 may be assisted by one or more nearby communication devices such as the nearby communication devices 104 during the discovery session. The nearby communication devices 104 may assist the discovering master communication device 102 by accessing one or more capabilities used to identify availability of the high resources consuming wireless network 110 and/or the remote resources 115, for example, sensory data and/or calendric data. The sensory data may be available from one or more sensors accessible by one or more of the nearby communication devices 104, for example, GPS, accelerometer and/or gyroscope. The calendric data may be available from one or more calendric records available to one or more of the nearby communication devices 104, for example, calendar application, task management application and the likes.

As shown at 330 which is a decision point, the discovering master communication device 102 determines availability of a remote service. The remote service may be, for example, a high resources consuming wireless network such as the high resources consuming wireless network 110 and/or one or more remote resources such as the remote resources 115 based on the discovery process of 320. In case the remote service is available and a connection is successfully established, the process 300 branches to step 340. In case the remote service is not available and/or the discovering master communication device 102 could not establish a connection to the remote service the process 300 branches to step 350.

As shown at 340, in case the discovering master communication device 102 resolves remote service is available and accessible, the discovering master communication device 102 may send an availability message to the nearby communication devices 104 over a low resources consuming communication link such as the low resources consuming communication link 120. Following reception of the availability message, the one or more nearby communication devices 104 may enable their high resources consuming wireless interface to connect to the remote service.

As shown at 350 which another decision point, in case the remote service is not available and/or not accessible, a decision is taken whether to assign a different one of the nearby communication devices 104 as the discovering master communication device 102 or to leave the current the discovering master communication device as the discovering master communication device 102. The decision at 350 may be based on a resources analysis as described hereinabove. In case the discovering master communication device 102 is decided to maintain the role of network discovery the process branches back to 320.

As shown at 360, in case a candidate of the nearby communication device(s) 104 is determined to be assigned the network discovery role where the candidate is not the discovering master communication device 102, the discovering master communication device 102 sends a master assignment message to the determined candidate over the low resources consuming communication link 120. The determined candidate now becomes the discovering master communication device 102 and it carries out the network discovery session starting at 310.
